Description

Application

2-Butyne-1,4-diol is extensively used in the cycloaddition reactions such as the homologation method for the preparation of substituted acenes, rhodium and iridium-catalyzed [2+ 2+ 2] inter and intramolecular cyclotrimerization. It can also be used in the total synthesis of (−)-isolaurallene, (−)-amphidinolide P and bistramide A.
